What should I do about this rash around my belly button after tummy tuck? (Photo)

There can be many causes for your rash. It looks like a fungal rash. However, without an assessment it is impossible to say for sure. Contact your surgeon. Regards, 

This is either an allergic reaction to the tape that was used or possibly a fungal rash. I would recommend a steroid containing fungal cream like Mycolog. You should definitely check with your plastic surgeon and follow their recommendations. Good luck!

Thank you for sharing your photographs and question.  This area of redness does appear to be an allergic reaction based on the appearance and pattern as well as your narrative of gauze and soap use. Gentle washing of the area, intake of benadryl or oral steroids, topical ointments or steroid creams should all help alleviate your symptoms. Make sure you have close follow up with your surgeon to ensure steady improvement until complete clearance takes place. Hope this helps.

Hello, Thank you for your question. I'd recommend contacting your Board Certified Plastic Surgeon directly for their recommendations. All the best. 

I would see your PS for an examination and advice. It looks like dermatitis and possibly due to a reaction to a dressing?  

There can be many causes for your rash, and common ones are sensitivity to topical medications or adhesives. Infection cannot be ruled out without an exam, nor can we recommend treatment. Common practice tells us to clean the area with a mild soap such as Ivory, stop ointments, and call your surgeon to take a look.

Thank you very much for your question.I recommend you contact your plastic surgeon and see what they want you to do.  I wouldn't want to advise something that is against your surgeon's wishes.
